7 ments ofw'this kind, and to rovide asimpleand efllcient coupling whic shall have advantages over such devices as are now warren w. .xaraor'ronxn'ns, ns'w roan.

Be it known that I, WALTER W. Knrs, a citizen of the United States, and a resident of .the city of Yonkers in .the countyof Westchester and State 0 New York, United States of America, have invented certain new and useful Improvements in Hose- Couplings, of which t "fication.

My invention relates to hose couplings; and its object is to improve upon arrangeknown.

' I willdescribe invention inthe followthe con ing specification and point out the novel features thereof in the appended cla'imsl Referring to the drawings, Figure 1 shows -in side elevation a portion of a hydrant with a hose attachdthereto bymeans of one of my improved couplings. Fig. 2'is-a sec.- tional side elevation of the coupling'with its parts together.-

3 'is aside elevation of the'same parts in 'difi'erent relative positions and with the inner member of g shown in section. Fig. 4 is a sectiona end view of the coupling.

Like characters of reference designate corresponding parts in all of the figures. f

10 designates the inner end of a coupling which may be threaded at '11 so that it may be afixed to a hydrant 12, or to the end of a pipe or hose, or to other desired fluid conductor. The. portion 13 outside of this threaded art may be made with flattened faces or ot erwise arranged tobe acted upon by a wrench. Immediately in front of this ortion 13 the mernber 10 is constructed to orm an annular collar 14; in which two or more locking ockets 15 are provided. These pockets are c the peculiar form shown and adapted to ceive and to fit locking In which I will escribe later. The rest of this inner mem r is carried forward in the form of a hollow cylinder 16 from the outer surface of which projects segmental threads 17. -20 is the outer member. of the couplin I This is a c lindrical shell one end of whic is thread v at 21 for the reception ofja hose 22, or, pipe, or'an other-devlce'which is to be conuected'by t e coupling. 23 is a'collar formed on the outer portion hf the member.

directly back of. this threaded part. From the inner surface of this member 20 pro'ect segmental threads 24 which are arrange to. engage with'the segmental threads 17. The

"outer surface 25 ofthis member from the collar 23 back is a smoothcylinder from which project lugs 26. 3O isa locking collar which is fitted over this cylindrical surface of the member 20 andis arranged to be moved rotatabl and longitudinall thereon. This locking co lar is'provided wit internal .rccessesas shown at 31 for the reception of compression springs 32'. These-springs abut against the lugs 26 and tend to rotate the collar about the outer member 20 until the ends33 ofgits recesses come in'contact with these This lockin collar has projectirrgirom one ofits si es locking lugs 34 which corres 0nd in shape and in number with the'poc 'et s 15 in the inner" member 10. The pockets are, however, .cut away so; that the lugs'may be thrust into them but after ward turned so that a portion of each of pocket. The'outer surface of the locking collar is preferably knurled to facilitate its operation.

Thepartsof this device have been pointed out and I will now describe the manner in which it. is used. 1 Let us assume thatthe. part 10 is upon 'a hydrantand that the 'part 20 is upon the end of a hose. The outer member isfirst thrust over the inner member. The segmen-- tal threads 17 and 24 are each somewhat less than one quarter-of thecircumference of the surfaces from .whichthey project so thatthe two main arts of the coupling may be thus ut toget er.- A packing ring 27 may be p aced within the .member 20 against which the end of the part 16 ofthe inner member will seat when the inner and outer members are thus broughtrtogether; A shoulder is formed within the member 20 to support this packing. Thispart of the opthe locking collar. T

In the first place, through the compression springs 32 it rotates the outer memer in relation to the art upon the hydrant to force the threads 1 and 24 together and to push the part 16 of the inner member cu'rely locked together.

as has been pointed out, are

against the ackin'g." This, at the same time,

that the pressure of the springs is now opposed by both the inner and outer'members in-the directions which tend to force their segmental threads together. This operation has been described quite at length in order to clearly set forth the invention, but the instantaneously.

entire operation may be accomplished almost This coupling forms :1 erfectly t-igh't joint which is capable of withstanding great pressures. Internal pressures have no tendency to loosen the connection thus made, but thecoupling may be readily disconnected at willby simply reversing themanual operations above described.

This invention is especially adapt-able for use with fire hose as it fulfils the need of something whereby a tight connection may and which is simple in consti'uction-and not at all likely to get-out oforder. But the invention, limited tothis specific use.
